"Oh, my boy, my dear boy," interrupted the other with amused patience; "you don't know what you are saying. I know what you are suffering. I have loved too, not so violently perhaps as you; perhaps as sincerely—at any rate with all my soul—and I ran away—ran away from happiness, because I would not inflict an invalid on the woman I loved, nor make her the mother of sickly children; and so for this world we said good-by, and I am here alone—alone—except for God."

Hal was very still. It meant a great deal to him that John McCloud had taken him behind the curtain. He realized that it was a supreme test of the other's affection, and he felt ashamed that he should have taken for granted so much that was childish in assumption and offensive in its condescension. In the presence of the other man's sorrows his own seemed dwarfed and commonplace. When his voice was steady he said: "Then you know; yes, you know." And McCloud understood what he would have liked to say but couldn't.

"Does Wah-na-gi know?" he asked relentlessly.

"No, I couldn't tell her; but I will."

Swiftly it passed through McCloud's thought: "Is this a house built upon sand? Would this lad run straight? Would he stand the test? Would he swerve under pressure? Or was he one of those infirm of purpose, who take cycles of infinity to develop into a man—God's man?"

"My boy," he said gently; "you must make a calm, relentless examination of your own soul. You must not forget that you are a white man. You have Indian blood in your veins, it is true, but you were born and bred a gentleman. Have you thought of that?"

"Gentleman?" said the boy bitterly. "I'm a half-breed. I've never been allowed to forget it."

It was the first time McCloud had ever heard him use the odious term, and the expression of his face, the tone of his voice, opened up a vision of a journey made tragic with the burden of the cross and the crown of thorns. He knew for the first time what this boy had suffered and it filled his soul with pity. But he saw in the bitter past only a sign and prophecy for the future. Here was the wound. The boy had bared it and placed in his hand the knife. He must use it.

"Then you know, no one better than you, that there is nothing more cruel in a cruel world than race prejudice."

"And nothing more cowardly," flashed back the quivering victim.
